Question

我正在运行此程序，并在输入我的名字后继续收到错误

＆＃34; program1.exe已停止工作＆＃34;

不知道为什么有任何帮助？

#include <stdio.h>
#include <stdlib.h>
#include <iostream>

void create();
//void edit();
//void delete();
int main()
{
    char choice;
    printf("\n\t\t **********************\n\n");
    printf("\n\t\t Train Booking Application\n");
    printf("\n\t\t **********************\n\n");
    printf("Select 1 to create a booking,\tSelect 2 to Edit booking,\tSelect 3 to Delete a booking\n");
    scanf("%d",&choice);
    if (choice == 1){
        create();
    }

    return 0;   
}

void create(){
    char Fname,Sname;
    printf("Please enter your First name:\n");
    scanf ("%s",Fname);
    printf("Please enter your Second name:\n");


}

Answer 1

char用于读取一个字符。请改用字符串。％d用于读取整数，但是您定义了。使用

int choice;

或使用

scanf("%s", &choice);

尝试使用开关进行选择

switch(choice){
case 1:
create();
break;

case default:
//default statement(s)
}

请注意编译器警告。它会为你发现问题。建议改进计划意见：

#include <stdio.h>
#include <stdlib.h>
//#include <iostream> // C++ include, not needed!

void create();

int main()
{
    int choice; // changed to int to match scanf("%d", char is to small to hold an `int`

    printf("\n\t\t **********************\n\n");
    printf("\n\t\t Train Booking Application\n");
    printf("\n\t\t **********************\n\n");
    printf("Select 1 to create a booking,\tSelect 2 to Edit booking,\tSelect 3 to Delete a booking\n");

    scanf("%d", &choice);

     switch (choice){        // switch is a better choice than nested ifs
         case 1:
             create();
         break;

         default:
         printf("not implemented yet...\n");
         break;
     }

    return 0;   
}

void create(){
    char Fname[256],Sname[256];  // changed to arrays to match scanf ("%s"
    // char Fname, Sname with %s would destroy memory 
    printf("Please enter your First name:\n");
    scanf ("%s",Fname);
    printf("Please enter your Second name:\n");
    scanf ("%s",Sname);
}

Answer 3

由于char只存储一个字符并且您的名字长于此字符，请尝试使用 char Fname [] 来存储您的全名。

.exe已停止工作（Cprogramming）
